Description
A deep blue to violet-black triggerfish with a paler blue-green head, bright blue fin margins, a lyre-shaped tail with long trailing lobes, and distinctive red teeth; color shifts from teal to near-black with mood and lighting. It swims constantly in open water with a propeller-like sculling of the dorsal and anal fins, so it needs a long tank with strong flow, big open swimming lanes, and rockwork caves to bolt into at night. One of the more even-tempered triggers, it is still a large semi-aggressive fish that grows fast, may bully smaller or slower tankmates, and will pick at shrimp, snails and small crabs even though it largely ignores corals.
